Scrapper

Several Scrapper drones were hiding under the surface of Earth's Moon with scores of other Decepticon troops. Once the Autobot traitor Sentinel Prime and Megatron activated the space bridge pillars, he and other Decepticons were able to cross over from the Moon into the middle of Washington D.C. The Scrapper drones then participated in the subsequent invasion of Chicago. During the climatic battle in Chicago, they were all killed - though one was notably killed by Optimus Prime's energon sword when he came charging down the main battlefield.
